 first and second staple portions joined together at ends thereof at a junction so as to define an included space; 
 said first staple portion including structure for engaging a staple support, said structure comprising a slot, said slot comprising a large diameter portion and a small diameter portion, said slot being distanced from the junction; 
 said second staple portion comprising structure for engaging a canal, wherein said structure for engaging a canal comprises a projection for piercing said canal, said projection extending into said included space.
